Famous and popular Malossi 70cc Cylinder Kit "MHR Team II 2012" Piaggio NRG / Runner- one of the most powerful 70cc "Hyper Racing" kits on the market, not least due to superior workmanship and HQ materials.

The "MHR Team II 2012" has a different exhaust port design than its predecessor. It was completely modified and adjusted to fit the exhaust flange (included). The cylinder has 7 transfer ports and a bridged exhaust port; it comes with a single-ring piston and a high-compression modular cylinder head.

This kit will give you 21hp (or more) out of the box, providing that it is run with the right components ("Hyper Racing" exhaust, racing ignition, 28mm carburetor etc.).

Note: You'll have to mill the crankcase to make room for the cylinder base (see manual for detailed instructions).

As with all aluminium cylinders, you'll have to adjust squish clearance for maximum power and reliability.
